Basic and diluted earnings per share |
Basic and diluted earnings per share | ​ 9 Basic and diluted earnings per share ​ Basic net (loss) / income per ordinary share is computed by dividing net (loss) / income for the period by the weighted average number of ordinary shares outstanding during the period. Diluted earnings per ordinary share are calculated by adjusting the weighted average number of ordinary shares outstanding, assuming conversion of all potentially dilutive ordinary shares. For the three and six months ended June 30, 2021, dilutive net income per ordinary share is computed using the treasury method. As the Company has incurred a loss in the three and six months ended June 30, 2022, all potentially dilutive ordinary shares for these periods would have an antidilutive effect, if converted, and thus have been excluded from the computation of loss per share for the three and six months ended June 30, 2022. ​ The potentially dilutive ordinary shares are summarized below: ​
